ROSIN CAKE.

Specification of Letters Patent.

Patented May 26, 1914:.

Application filed August 21, 1913. Serial No. 786,046.

To all whom it may concern.

Be it known that I, DIN C. LOHMANN, a citizen of the United States, anda resident of West Milton, in the county of Miami and State of Ohio,have invented a new and Improved Rosin Cake, of which the following is afull, clear, and exact description.

My invention relates to a cake of rosin for use in connection with thebows of stringed musical instruments, and it is a design of my inventionto provide a rosin cake having sections of soft and hard rosin, the softrosin serving to hold the hard rosin to the bow. In the preferred form Ifurthermore incorporate bluing in the soft sect-ions of the cake, sothat the application of the rosin will whiten the bow. Also, it isdesirable in practice, that the sections he so arranged that the softsections will be confined by the hard sections.

Reference is to be had to the accompanying drawings forming a. part ofthis specification, in which similar characters of reference indicatecorresponding parts in both views.

Figure 1 is a perspective view of a rosin cake formed in accordance withmy inven tion, showing the same in the usual open ended box; and Fig. 2is a perspective view of the cake in a slightly modified form.

In the form shown in Fig. 1 the rosin cake is shown molded in a box. 10and comprises two end sections 11 of hard rosin, and an intermediatesection 12 of soft rosin. By the arrangement, the end sections 11 of thehard rosin serve to confine the soft rosin and maintain its form.

In the form shown in Fig. 2, there are end sections 11 of hard rosin, acentral larger section 11 of hard rosin, and alternating with the hardsections are sections 12 of soft rosin. The sections 12 are designed toe of softer rosin than the single section 12, it being my purpose tomake up cakes having layers of difierent degrees of softness, and thesofter sections are desirably smaller in order that they may bettermaintain their form.

In both forms it will be observed that the hard sections are at the endsand confine the soft sections. Furthermore, in practice, I incorporatebluing in the soft sections so that the application of the rosin to thehow will whiten the latter. The use of the softer rosin also prevents,as far as possible, the dusting of the instrument.

The rosin is applied to the bow in the usual manner, and the soft rosinwill the more readily adhere to the bow and will, in turn, serve tocause the hard rosin to better adhere.

Having thus described my invention, I claim as new, and desire to secureby Let ters Patent:

1. A rosin cake, comprising sections of relatively hard and soft rosin.

2. A rosin cake, comprising end sections of hard rosin, and anintermediate section of relatively soft rosin.

3. A rosin cake, comprising sections of relatively hard and soft rosin,the soft rosin having bluing incorporated therein.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
